简要总结
Proliferative lupus nephritis (LN)is the predominant cause of morbidity and mortality in juvenile Systemic Lupus Erythematosus (SLE). Induction therapy with high-dose intravenous cyclophosphamide can improve renal outcomes, but considerably associated with infection. Although severe infection is the significant complication related to poorer prognosis for juvenile SLE patients in Asia, cyclophosphamide is still commonly used as the drug of choice for severe lupus nephritis. Euro-Lupus Nephritis Trial demonstrated low-dose intravenous cyclophosphamide regimen followed by azathioprine achieved good clinical results comparable with obtained high-dose regimen. There was lower number of severe infection episodes, but no significant difference. Recent studies applied low dose of cyclophosphamide (500 mg/m2/dose or 500 mg/dose)in young patients and showed good renal response. Low-dose intravenous cyclophosphamide regimen might promote non-inferior renal remission whereas decrease risk of serious infection and improve overall patient outcomes.

研究组 & 干预措施
Low-dose intravenous cyclophosphamide
Low-dose intravenous cyclophosphamide 500 mg/m2/dose every 4 weeks/months for 7 doses. Total duration is 6 months for the induction treatment.
干预措施: Low-dose intravenous cyclophosphamide (Drug)
High-dose intravenous cyclophosphamide
High-dose intravenous cyclophosphamide 1,000 mg/m2/dose, the first dose will be started with 500 mg/m2/dose and steped up to 750 mg/m2/dose for the second dose. Then the dosage will be increased to 1,000 mg/m2/dose for the third dose and continued the dosage through the seventh dose. Total duration is 6 months for the induction treatment.
干预措施: High-dose intravenous cyclophosphamide (Drug)
结局指标
主要结局
renal response
时间窗: at 6 months of the treatment
3 main renal parameters: renal function(eCCl),proteinuria(spot urine protein/creatinine ratio, UPCR), and urine sediment (rbc,wbc,and casts) 'renal remission' * complete- normal renal function, UPCR\<0.2, and normal urine sediment(rbc\<5,wbc\<5/HPF,and no cast) * partial- at least 50%improvement in 2 main parameters with UPCR \<= 1.0 and without worsening of remaining main parameter
次要结局
- infection(within 6 months)
